Watched that before, good graphics but . . .
With the stars moving away from the viewer one expects them to get smaller anyway. This distracts from the actual visual size comparison, a side-by-side line with a parallel tracking camera, pulling back but with all the line always in view, effect might have been better. O K, the planets soon get too small to represent, but that is part of the picture - on the universal scale we live on an insignificant, microscopic blue dot.
